I hope my 02s are bad... with logs

Hey guys, after driving for a hour or so i get a service engine light, codes are below, i have logs attached, true fbo on stock flash.

29EO - DME: Mixture control.
29E1 - DME: Mixture control 2.
ZAAF - DME: Fuel pump, plausibility.
2C7B - DME: Oxygen sensor after catalytic converter: Signal.

I have had ZAAF for over 4 years since i bought the car.
I also have cat conversion on both banks because i have downpipes.
I hope its a faulty oxygen sensor
